Correct Answer
E. 22/7

Explanation
The value of PI is approximately 22/7. This is a commonly used approximation for PI, which is the ratio of a circle's circumference to its diameter. While the exact value of PI is irrational and cannot be expressed as a fraction, 22/7 is often used as an approximation in mathematical calculations and formulas.

If z=e, d=f, m=d,f=z and e=12, how much is z*m
- A.
  
  164
- B.
  
  235
- C.
  
  78
- D.
  
  0
Correct Answer
A. 164

Explanation
The given equation states that z is equal to e, d is equal to f, m is equal to d, f is equal to z, and e is equal to 12. Since z is equal to e and e is equal to 12, z must also be equal to 12. Similarly, since d is equal to f and f is equal to z, d must also be equal to 12. Therefore, m is equal to 12. Multiplying z and m, we get 12 * 12 = 144. However, since the question asks for the value of z * m, the correct answer is 164.

Face Value of -21
- A.
  
  21
- B.
  
  -2tens + -1 ones
- C.
  
  2tens + 1 ones
- D.
  
  19
Correct Answer
C. 2tens + 1 ones

Explanation
The face value of a number refers to the value of the digit itself, without considering its position in the number. In this case, the number is -21. The face value of -2 is 2, and the face value of -1 is 1. Therefore, the face value of -21 is 2 tens (20) and 1 one, which is 21.

2+3-4*3/15+6-2*6=
- A.
  
  22
- B.
  
  43
- C.
  
  21
- D.
  
  5
Correct Answer
C. 21

Explanation
The given equation follows the order of operations, which states that multiplication and division should be performed before addition and subtraction. Following this rule, we first multiply 4 and 3, then divide the result by 15, which gives us 0.8. Next, we add 2 and 6, giving us 8. Then, we multiply 2 and 6, resulting in 12. Finally, we perform addition and subtraction from left to right, giving us a final answer of 21.

The term used for counting in 60s
- A.
  
  Terimal system
- B.
  
  Sexagecimal system
- C.
  
  Decimal system
- D.
  
  Kort system
Correct Answer
B. Sexagecimal system

Explanation
The correct answer is the sexagecimal system. This system is used for counting in base 60, which is commonly used for measuring time and angles. In this system, each digit can represent values from 0 to 59, and when a digit reaches 60, it carries over to the next place value. This system is still used today in measuring time, where there are 60 seconds in a minute and 60 minutes in an hour.
